Events: Remove unused channel from EventHandler context

This commit removes a channel that became unneccessary
after the refactoring of the events server and is
preventing garbage collection of the handler struct
when it goes out of scope. It also adds back the
return of an error upon an errant send which will
close the chat processing loop
